I tried to refind the article so I could post a link,but,no such luck.The article tested shortys,mid-length,& longtubes on a dyno.The shortys were the type that use stock exhaust hookups w/ 2 1/2" collector.The mid-length had a standard 3" 3 bolt header collector.I can't remember the actual gains from each offhand.Naturally the longtubes made a lot more torque & power,but,only @ higher RPMs.At lower RPMs there wasn't much difference.The type of shortys used really didn't make enuff difference to justify the costs & work to put them on @ any RPM .At higher RPMs,the mid-lengths made approx half the gains as the longtube. If I can find the article,I'll post a link.
